Five students took a math test before and after tutoring. Their scores were as follows.
subject A B C D E
Before 71 66 67 77 75
After 75 75 65 80 87
Using a 0.01 level of significance, test the claim that the tutoring has an effect on the math scores
How can I solve this question? Can I solve this question using ti83?
Homework Answers
Let us denote the difference
d = Before - After
Conclusion :
There is not sufficient evidence to support the claim that the tutoring has an effect on the math scores.
To calculate critical value in TI 83, command : invT(0.995, 4)
To calculate P-value in TI 83, command : 2*tcdf(E-99, -2.134, 4)

A principal of a middle school wants to investigate whether student performance on a math test depends on instructor of the class. She selects 18 random students and assigns each of them randomly to one of three different instructors. The test scores are given below. Is there sufficient evidence to conclude that student performance differs between instructors? Use significance level 0.1 Note that the numbers in this problem have been manufactured such that all of the group means and the...
